This little brown Goomba (aka Gumba) mushroom-like creature has two dark brown feet, bushy, black eyebrows and a pair of fangs sprouting from their lower jaw. He is one Bowser’s army troop with only one mission…. defeat Mario! Goombas take inspiration from the real-world shiitake, a type of mushroom. Mario. He’s willing to take one for the team by simply bumping into their target to damage them.
